2 Basic Safety Information
Please heed the following safety information before engaging
in any activities.
2.1 Product safety
The universal joint shaft has been developed and built according to
the state of technology as well as the applicable safety regulations
at the time it was put on the market.
Nevertheless, its use can result in danger to life and limb of the
user or damage to the universal joint shaft itself and other property.
Only install the universal joint shaft if it is in proper condition
and only for the designated use, in a safety-conscious
manner that complies with the instruction manual.
Immediately correct (or have corrected) any defects that
adversely affect safety.
2.2 Proper use
Universal joint shafts transmit torques between defined drive and
machine components. Therefore, the universal joint shaft is
intended for installation in the specific machine/system for which it
was selected.
Any other use, especially installation in other machines, is not
proper and forbidden.
Voith universal joint shafts are not approved for use in the food
industry.
In liquid media, universal joint shafts may only be used with written
permission of the manufacturer.
The universal joint shaft type we make and size can only be
regarded as recommendations.
Any improper use or activities on the universal joint shafts not
described in this instruction manual are impermissible misuse
outside of the legal liability limits of the manufacturer.
Heed the following measures to avoid misuse:
Only operate the universal joint shaft within the specified
speed and torque range.
Foreseeable misuse

Universal joint shafts are resiliently-flexible bodies that are
designed for bending vibrations and bending-critical speeds.
Therefore, for safety reasons, the maximum operating speed
must be significantly below the critical-bending speed 1st and
2nd order (see universal joint catalog G830).
For sufficient balance and security for the universal joint
shaft, it must be ensured that the operating speed does not
exceed the maximum permissible value depending on the
shaft angle (see universal joint catalog G830) and that the
driving and driven system parts are aligned with one another
(plan and concentric run-out see page 40)
Do not exceed permissible shaft angles of the universal joint
shaft.
Adhere to the lengths and temperatures specified for the
selection of the universal joint shaft.
For universal joint shafts with length compensation, make
sure that the maximum permissible movement path is not
exceeded.
A local heating of the universal joint shaft, e.g. due to the
burning off of old color remnants is not permissible in order to
change the run-out properties.
Protect components coated with Rilsan against too-high
temperatures, chemical solvents, steam, and mechanical
damage.
Attaching parts to the universal joint shaft by welding or other
connection types is not permissible.
Adhere to the manufacturer's specifications with respect to
operation, maintenance, and repairs.
Have work on universal joint shafts done by the manufacturer
or by service technicians authorized by the manufacturer.
Do not make any unauthorized modifications or changes.
In areas subject to explosion (atmosphere), only use ATEX-
certified universal joint shafts. Here, heed certification (Chapter
3.1, page 22).
2.3 Remaining risks
Before beginningconstruction and planning, the remaining risks of the
universaljoint shaft were analyzed and evaluated.
Remaining risks that could not be avoided during the entire life cycle
of the universal joint shafts are:
